GC/G
Guess I didn't know how to take it, that night we had that talk
GC/G
Found out about my replacement, I just smiled and shook it off
GC/G
I didn't ask you any questions, didn't beg you to stay
Am7C
You said you knew that I would understand, then I watched you drive away
When there's just no words to stay
GD
I scream at the top of my lungs
Em
Yeah, I come undone
DC
I crash like broken glass when no one's around
GD/F#
I cry out, in the silence I can't take
EmDC
To cover up the sound it makes when I let my heart break
GG/BC
I scream
GG/BC
I scream
GC/G
I always say the right things, at all the right times
GC/G
I know I'm not the perfect girl, but for some reason I try
GC/G
To be the one who's smiling and laughing, to make sure everyone's okay
Am7C
I can push those tears back inside like an actress on a stage
But when the curtain falls away
GD
I scream at the top of my lungs
Em
Yeah, I come undone
DC
I crash like broken glass when no one's around
GD/F#
I cry out, in the silence I can't take
EmDC
To cover up the sound it makes when I let my heart break
GG/BC
I scream
GG/BC
I scream
D
I can't hold it in no more
B/D#
I don't feel like playing nice
Em
When I feel like getting loud
DC
I just gotta let it out
I just gotta let it out
GD/F#
I scream at the top of my lungs
Em
Yeah, I come undone
DC
I crash like broken glass when no one's around
GD/F#
I cry out, in the silence I can't take
EmDC
To cover up the sound it makes when I let my heart break
GG/BC
I scream
GG/BC
I scream
GG/BC
I scream
GG/BC
I scream

Good tab, the only thing I would mention is the original song key is not in G, it's a semi - tone lower in F#. Her guitarist plays this in D with a capo at the 4th fret.Use the transpose function down to -5, and you have the right chords.
